Abstract
A display tag is provided. A display tag includes a sensing unit which captures an image displayed on a screen of an external tag writer, if a sensing unit is disposed opposite the screen; and a display unit which displays a captured image. Therefore, a user can visually recognize content related to tag information, and thus user convenience is enhanced.
